An aluminum joint is clamped using an M8 x 1.25 class 10.9 fastener with rolled threads;...
Ajoint is composed of a ¾ in.-16 UNF fastener (Steel Grade 5) with cut threads clamping 2 Aluminum plates. The clamped members are 5 times stiffer than the bolt. If the initial preload is 80% of the bolt's proof load, what is the service load that would cause joint separation? Assume that the extemal load is applied at the exact location of the bolt (bolt load factor n-I The fastener in the joint analyzed in Problem 1 is tightened to...
A ¾ in. UNF, grade 7 bolt with rolled threads is used in a joint having a soft gasket for which the clamped member stiffness is only half the bolt stiffness. The initial bolt tightening corresponds to Fi= 16000d, where d is in inches and Fi in lbs. During operation, there is an external separating force that fluctuates between 0 and P. Assuming a design factor of safety of 2: a) Estimate the Maximum P that would not cause eventual...
[3]. (3 marks) Figure below shows a bolted joint subjected to an external force P that fluctuates from 0 to 7 kips The steel bolt specification is 5/8"-11 UNC, SAE grade 5 material with rolled threads. The clamped members are steel of length 1.25 in each (with a total length of 2.5 in). Plain wide washers are utilized at both ends of the bolt. [a]. Using the Goodman line, determine the factor of safety guarding against fatigue failure for the...

For a bolted assembly with eight bolts, the stiffness of cach bolt is k 1.0 MN/mm and the stiffness of the members is k26 MN/mm per bolt. The bolts are preloaded to 75 peroner of proof strength. Assume the external load is equally distrihuted to all the bolts. The bolts am M6 x1 class 5.8 with rolled threads. A fluctuating external load is applied to the cntire with P 60 kN and P - 20 kN. (a) Determine the yielding...
